To @ZZ whom, t may concern.-

Be it known that I, ERIK MANULA, a citizen of the United States,residing at Astoria, county of Olatsop, State of Oregon, have inventedan Improvement in Can-Soldering Machines; and I hereby declare thefollowing to be a full, clear, and exact description of the same.

My invention relates to improvements in can-soldering machines.

It consists of an adjustable feed device, acid-trough, and solder-troughin line and in diiferent planes and adjustable with regard toeach other,two spirals of different length axially in line and parallel to the twotroughs, the one governing the advance of the cans through ltheacid-bath having a revoluble shaft or can-support, and the one governingthe advance through the solder-bath having an eccentric and fixedcan-support.

It also comprises details of construction that will be more fullyexplained in the following specification and drawings.

Figure 1 is a plan view of the machine. Fig. 2 is an elevation of thesame. Fig. 3 shows the entrance into the hollow spiral. Fig. 4: is anend view of the feeding device. Fig. 5 is a lateral section on line 0cof Fig. 1. Fig. 6 is a similar section on line y y of Fig. l. Fig. 7 isan enlarged sectional detail of a portion of the trough B, showing theinclined plate 5. Fig. 8 is a cross-section of the same on the line fr,x.

A represents the frame or bed of the machine.

B is the acid-trough. It has a reservoir 2, from which the liquid flowsover the lip 3 into the groove 4t, in which the tins dip. The bed-plateof this trough is transversely slotted, as at 38, and is secured to thebed A by setscrews 39. C is the solder-trough. These troughs areessentially horizontal and of sufficient length so that all parts of thearticle to be soldered can be made to dip successively into the bathswhile moving from one end of the bed to the other. The trough B iselevated about two inches above the solder-trough O, and the inner upperedges of these troughs are connected by an inclined plate 5.

D is a spiral centrally journaled at 6 and 7. E is a second and longerspiral having the same axial line asD and the common journal 7 andjournaled at the opposite end at 8. The shaft of the spiral D attachesat 9 to the shaft of the spiral E, so that the same power drives andturns both in unison. The turns of these spirals are sufficient to admitthe cans which are to be soldered. The spirals' are capable ofreplacement 'by others of different size where varying diameters of cansare to be operated upon. The spiral D, which is arranged in relation andparallel to the acid-trough, has a shaft 10, revoluble with the spiral.The edge of the trough B is just enough below the plane of the upperedge of the shaft 10, so that a can resting upon both will dip at theproper angle into the acid. The spiral E, which is arranged in relationto the solid trough, is hollow and incloses a fixed shaft 11, lyingbelow the center of the spiral and for the greater part of its lengthparallel to the axis of the spiral. -Near where the two spirals arejoined the shaft 11 turns upwardly and parallel to the incline 5 and isfastened in the journal-support'of 7 and at the opposite end is attachedto the journalsupport of 8. This shaft is slightly above the inner edgeof the solder-trough, so as to incline the cans properly thereto. Thespiral D is shorter than the spiral E, as the trough B is shorter thantrough C, for the reason that one revolution 0f a can in the acid issufficient and, in fact, preferable, whilein the solder it is desirablethat the can be made to revolve a number of times and take up sufficientsolder to make a perfect seal.

F is an adjustable solder-bar or guide-bar. Its ends rest 'upon the endedges of the soldertrough. On its lower side and extending the innerlength of the solder-trough is a downward extension or angle-plate 12.Ribs or supports 13 are cast in the trough at intervals and support theplate 12, and prevent the bar F from sagging. To the bar F are attachedarms 14, haivng slots 15, through which pass locking devices 16, andwhich latter attach arms 14 to the bed, by which the bar F may beadvanced or withdrawn over the edge of the trough.

F F2 are parallel bars held upon the posts F3 and all forming the guidepart, called for convenience F.

The spirals are driven by gearing, as at 17.

IOO

1S is a shaft connecting therewith, having the power-pulley 19 andcarrying the eccentric or cam 20. Resting upon this cam and held theretosimply bygravity is the lever 21. The other end of this lever is xedlyattached to a shaft 22, journaled at 23 and 24, which latter are part ofthe hase-plate 25. The plate 25 has a slot 26 and is held in positionupon the bed A. by the bolt 27. Upon the shaft 22 is the feed-plate G,fastened as at 2S. Rear# ward of 28 is aline of perforations up throughwhich extend the im peding-pins H. The baseplate 25 referred to is ofcast metal,having an angular extension 29 parallel to the shaft 22. Upon29 and at right angles thereto, are flanges 30 and 31. The incline of 29is such as to conform with the incline between the shaft 10 and theinner edge of B, previously mentioned, or, in other words, at the angleat which the cans are desired to dipinto the acid, dac. The flange 30 isa guide-wall, against which the cans rest as they are slid into thespirals. The plus H are fastened in the plate 29. Upon the upper edge of31 is a parallel guide J. This is made of angle-iron 32, upon which areriveted the parts 33,havi ug the longitudinal slots 3i. Guide J is thenremovably attachable to 31 by screws 35. `The adjustment of guide .l inrelation to the guide-wall 30 is determined by the length of can, andthe face of angle-iron 32 is of about the same length as that of flange30, and the purpose of these two guides, as seen, is to steady the canwhile the plate G is raised and to preserve it in proper alinement inentering the spiral.

The length of the weight of the cans carried While in operation cause avibration that to overcome I have shown a roller K. This roller isjourualed at its ends at 36 upon supports 37, and rests lightly againstthe outer peripheryof the coil.

Having described the details of the machine, its operation would be asfollows, supposing we are to work with tall cans: The solder-bar F isdrawn out to the outer edge of the solder-tro ugh, the acid-trough ismoved away from the spiral, the bolt 27 is loosened, and the plate 25,carrying the feeder, moved outwardly. The lever 21, resting taugentially to the shorter radius of the cam 20, shows theplate G, with thepins H projecting above said plate. A can is placed upon the plate andbehind the plus, with the end to be soldered against the wall 30 and theguide J near but not touching the other end of the can. The shaft 18 isrevolved, the lever 21 is lifted, and the plate G tilted till the heightof the pins above this plate is so reduced as to allow the cans to rollforward bet-Ween the guides 30 and J into the acid-spiral. One end ofthe can will there rest upon the inner edge of the acid-trou gh and theother on the shaft 10. The cans lying upon the supports are advancedfrom one end to the other by turning the spirals, and the cans arerolledor turned upon these supports so as to have the hollow spiral Eand they full circumference of their edges submerged iu the acid.Passing from the acid-trough and the shaft 10 and to the spiral E, thecan follows, by the parallel incline of the before mentioned upturnedpart of the stationary rod 11 and the part 5, into the solder-bath. Thesolder-bar F, the acid-trough, and thc guide 30 of the feed devicehaving, as said, been adjusted in relation to cach other and so thattheir connecting edges are flush and offer no projecting points toimpede the can act as a support to the outer end of the can throughoutits journey. The cans are delivered at the other end of thesolder-trough by any suitable means. To operate with short cans, theseguide parts are simply pushed iu closer to the spirals, and the cansinstead of resting partly ou the shaft 10 and the shaft 11 rest entirelyon the inner edge and against the outer wall of the acid-trough and onthe edge of the solder-trough and against the solder-bar F and arecarried forward by the revolving spirals, as before. The guide J is inthe latter case brought closer to the guide 30 and the cans are heldstraight, as before. As the revolution of the shaft 18 is the same asthe revolution of the spirals, the plate G is consequently lifted andlowered in unison therewith, and as a can is released at everyrevolution each successive space between the spiral convolutious isaccordingly filled. The action of the machine is thus made continuousand the timing is absolute and varies only as the speed of the coils.

Oval and irregular shaped cans are operated as in the foregoing cases.

In Fig. 5 the dotted lines represent short cans, whilein Fig. 6 thedotted lines indicate a tall can.

Having thus described my invention, what I claim as new, anddesire tosecure by Letters Patent, is.
